LAil'l-IING FOR PLASTERING.

SPECIFICATION forming part of Letters Patent 0. 721,074, dated February 17, 1903. Application filed September 30, 1902." Serial No. 125,375. (Nd model.)

To all whom it may concern;-

Be it known that I, JOHN D. OBRIEN, a citizen of the United States of America, and a resident ofthe city of St. Louis and State of Missouri, have invented certain new and useful Improvements in Lathing'for Plastering, of which the following is a'specification.

The present invention relates to lathing used in a foundation for a coat of plaster in building operations, and has for its object to provide an eflicient and convenient lathingsheet for such'uses and in which are combined the features ofreadyapplication to curved surfaces,a rapid, easy, and substantial attachment to the-underlying studding, and a surface to which the imposed coating of plaster will adhere in a very efiective and thorough manner to prevent subsequent checking and cracking of the plaster coat, all as will hereinafter more fully'appear and be more particularly pointed outrin. the claims. I attain such objects by the construction and arrangement of parts illustrated in the accompanying drawings, in which- Figure 1 is a plan view showing end fragments of two adjacent sections of lathing interlaced together in accordance with the present invention; Fig. 2, a sectional elevation of the same at line a; 00, Fig. 1; Fig. 3, an enlarged detail view at line cc w, Fig. 1.

Similar numerals of reference indicate like parts in the several views. 1

Referring to the drawings, 1 and 2 represent flat flexible strips of wood of an'extended width as compared to thickness and which in the present improvement are interlaced together to form a sheet of the present improved wood lathing of the required dimensions. By practical experience it has been found that a sheet of a sizethree feet by twelve feet is adapted for very convenient and effective application to the ordinary and usual arrangement of the 'studding and furringstrips in buildings. 1

The present sheet-lathing has especial advantage over the ordinary metallic lathing heretofore used in the'following particulars, to wit: Nails can be driven through any part of the sheet to effect a substantial attachment to the underlying studding or furring-strips,

and,-wl 1at is of still greatermoment, a surface is afforded to which the imposed. coating of plaster willadhere in a very intimate and effective manner to prevent the subsequent checking'and cracking of the plaster in the drying out of the same. The non-adherence of the plaster to the surface of metallic lathing and the consequent checking and crackihg ofthe'plaster coathas been a serious obstacle to an extended use of such lathing in the finer class of buildings.

3 represents rein force end strips arranged at the end of the sectionof lathing and which in the present improvement are secured to the cross-strips 2 in an individual manner by sheet-metal clips i or other equivalent means and in a manner to leave a free space between a reinforce-strip 3 anda companion end strip 1 for the reception of the interlacing strip, hereinafter described, by means of which two sections of lathing are connected together. n v v 5 represents clips securing the different strips composing the lathin'g together at the corners of the same.

'6 represents lacing-strips, of wood, having a thin and flat formation similar to that of the stripsl and 2 and of a comparatively short length. Such lacin g-strips are adapted to interlace two adjacent ends of lathing-sections together when the" same do not meet over a preferably by insertion in the free spaces heretofore described between the end strips 1 and 3. As so interlaceda continuous natu re is imparted to the different series of lathing-sections when applied, so that the securi ng of the same in place can; be conveniently and rapidly effected. The present construction affords a very light and substantial lathing-surface and which at the same time is adapted to be bent to fit curved surfaces in buildings either concave or convex in curvature. I

Having thus fully described my saidinvention, what I claim as new, and'desire to secure by Letters Patent, is-

1. As an improved article of manufacture, sheet-lathing consisting of flat flexible strips of wood, of an extended width as compared adapted to interlace with an adjacent section 10 with the thickness, interlaced together in an of lathing, substantially as set forth.
